The question of putative association between ridge pattern of the hand and human constitutional characteristics is still open, despite a long history of its study, because the results of different researchers are contradictory. Taking into account the relevance and insufficient consideration of the identified problem, this article examined intra-group variation of hand papillary patterns in connection with some aspects of morphological and functional status. In this study we used data from anthropological complex survey of 149 young males aged from 16 to 23, living in Mordovia and being of Russian and Mokshan ethnicity. The research program included registration of dermatoglyphic traits (number of triradii on the palm, fingers and the hand in general), body-build, body composition estimated by bioelectrical impedance analysis, functional features of respiratory and cardiovascular systems and hand dynamometry. Distribution of the number of hand triradii (and its separate parts) do not differ between Russians and Mokshans. Distribution of body-build characteristics in two groups is similar after age normalization. Due to absence of significant differences we combined all samples into one. The correlations between dermatoglyphic traits and morphofunctional measurements did not exceed 0.3, with rare exceptions. Being strongly genetically determined, both the number of all finger deltas and the total number of hand triradii, the latter largely depending on the complexity of the finger patterns, almost do not correlate with morphofunctional traits. Significant pairwise correlations are found mainly for the hypothenar and the general hand patterns – the areas of the hand which are more exposed to in-utero influences during the process of papillary pattern development. Factor analysis of all studied traits allows us to suggest a relative interdependence between dermatoglyphic and body-build characteristics. Co-variability of ridge patterns with a number of morphological and functional characteristics were identified only due to additional analyses of certain suites of traits. Thus, the overall dimensions and components of the body weight have weak direct dependence on hypothenar and ridge pattern of the palm in general. I.e. young males who have a tendency towards macrosomia or meso- and endomorphic constitution also have more triradii on the hypothenar and the palm area in general. Triraduii number on hypothenar shows weak positive correlation with the heart rate and measures of morphofunctional adaptation (the less adapted young males have the greater sum of triradii). Systolic blood pressure and heart rate also shows correlation with the total number of palmar triradii. Individuals with low relative metabolic level have a higher frequency of triradii on the palmar pads at the radius side. Probably these correlations are related to specificity of young male’s constitution. Thus, our results show relative independence between the hand ridge pattern and constitutional parameters. However, in spite of a small number of low level intersystem associations, we found some co-variation of palmar ridge pattern and some morphological and functional features. Thus, existence of weak correlations between body size or body composition and palmar triradii number is important because these results are consistent with data from other population and sex groups.
